Question

Which of the following species has unpaired electrons in anti-bonding molecular orbitals?
A. O2+2 B. N2-2
C. B2 D. F2

Answer 1

Answer:

HEY MATE HERE IS YOUR ANSWER .☺️✌.

Explanation:

◤⚠ OPTION B IS UNPAIRED .N2-2 BECAUSE IF THE ELECTRON OF NITROGEN IS SUBTRACTED THEN ITS DOESN'T REMAIN AS GAS .⚠◢.

HOPE IT HELPS YOU❤️❤️

Answer 2

Answer:

There are two unpaired electrons in B₂.

Explanation:

Two unpaired electrons in πbMO.

B₂ Contains 5+5=10e⁻=б1s²*б1s²б2s²*б2s²π2px¹≅π2p¹y

There are two unpaired electrons in a anti-bonding orbitals of B₂.

a) O₂²⁺ - they are having paired electrons.

b) N₂²⁻- it has paired electrons.

d) F₂- it has paired electrons

Pared and Unpaired:

• Unpaired electrons are the ones that appear in an orbital alone, whereas paired electrons are the ones that appear in an orbital as pairs in an atom.
• So, in the orbital, paired electrons always appear as two electrons, but unpaired electrons always appear as a single electron.
